I've got an LK204-25 and was wandering through a surplus store in Toronto and found a five button membrane keypad. Neat. It's got six connections... looks like one is the common GND, and the five are for the actual keys. There doesn't appear to be a common Ground connection on the 10 pin keypad connector, though, just five rows, and five columns as described in the manual.

I was planning to hook the common GND to row1 pin, and the five remaining to the column1-5 pins. Would this effectively work to send the signal down the serial line and into my LCD Smartie software?

...on that note, the LCD Smartie software refers to keypad1, 2, 3... 16 instead of responding to letters. Am I going to get this to work at ALL?

Thanks,
michael
